"They call it turf toe -- it's a little bit more than that," Spagnuolo said. "We've got a decision to make there."
Cornerback Kevin Dockery has a "significant" left-hamstring strain and might not play next week at Oakland, Spagnuolo said. Rookie tight end Michael Hoomanawanui has a high left ankle sprain that could sideline him a while.
Wide receiver Laurent Robinson was in a walking cast on his right leg after aggravating an ankle injury, although Spagnuolo said the MRI looked "pretty normal." Robinson caught a touchdown pass on the final play of the first half to tie the score, 10-10.
Running back Steven Jackson underwent an MRI exam on an inflamed right knee, but Spagnuolo believed the veteran would be fine.
